Polygon hair shader

Hello,
i’m having fun with hair mesh for game character.
Fun can have strange definitions, isn"t it ? :smiley:

I made this hair cut and shader.
I’m not convinced of the result, and losing patience trying to improve it.
There is always an issue, wichever setting and method i use.

I used 2 locks samples, each one has its own shader (in fact i made a slight variation of the first one in the second one).
The hair texture image is a .tga with alpha included, I hand painted in photoshop.
I desaturate it to use as spec and bump textures.

This is the last step to finish this character.
Here the development : https://www.flickr.com/photos/lollito/sets/72157641887106114/

Some feedback on this hair work would be much appreciated, and you get the polygon hair blend :-).

Nice blends to you !
